you wont need a relay mate
why do u need to put fans under the tmic ?!?
its pretty simple as you could have the switch under ya dash somewhere or in a blanker
you could even get one of the switches that light up when its switched on
ok all u have to do is mount up the fans and join their 2 wires together
black and red i think they are
both blacks together
both red together
and run thru bulkhead to your switch position
now put the black wires to ground
and get another piece of wirenot too thina dn not to thick
something like a speaker wire thickness should be good
and find yourself a 12v supply from round the dash area
you can get one from ciggy lighter, ignition or stereo, loads of diff places mate.
ok run a 12v feed to the switch where the red wires go to the other pin on the switch, so when the switch is in the on position you have ya 12v and red wires connected together.
i wire an inline fuse in there to be on safe side too
3amps should be enough or may b 5 depends on fan rating.
hope u follow this and its not too gobbledy gook

i dont know how he,s know,s if you need a relay or not 
it all depends on what current the fans take and what amperage your switch is , its always safer to fit a relay anyway plus you can buy them with built in fuses , so it will stop it going up in smoke
if you need help wiring a relay up i,ll email yuo the details
